“…Recently a small network of AP2/ethylene response factor (ERF) transcription factors was identified whose transcript levels rapidly respond to light shifts (Dietz et al , Moore et al , Vogel et al ). The AP2/ERF‐transcription factors RRTF1, ERF6 and ERF105 belong to this network and reach a maximal transcript level in WT plants within 10 min (Fig.…”

“…Retrograde control of nuclear gene expression elicits very fast changes within seconds but also long term responses on the time scale of hours and days. Within seconds after a major change in light intensity, metabolite signals deliver information on photosynthesis and energization state to the cytosol and with some delay alter gene expression on the time frame of minutes (Moore et al , Vogel et al ). Redox information from the plastoquinone pool feeds into a protein phosphorylation network (Dietzel et al ), which also controls long term acclimation by altering gene expression independent on cytosolic photoreceptors (Fey et al , Dietzel et al ).…”

Retrograde signals from the chloroplast control expression of nuclear genes. A large fraction of these genes is affected rapidly upon light intensity shifts. This study was designed to address the interdependence of signaling pathways involved in the rapid high light response and redox and reactive oxygen species signaling by exploiting the glutathione and ascorbate deficient mutants pad2 and vtc1. In the first set of experiments the transcriptional response of the two transcription factors ERF6 and ERF105 that had previously been shown to rapidly respond to light was shown to be deregulated in the pad2 mutant but not in the vtc1 background. The transcriptional response after combining the low-to-high light transfer with methylviologen pretreatment further demonstrated the significance of glutathione in strongly modulating the retrograde response. Transcripts encoding small heat shock proteins (HSP17.4, HSP176a, HSP20-like1 and HSP20-like2) and the lipid transfer protein LTP3 were taken as markers responding to the combinatorial treatment in wild type, and most strongly in pad2 in high light or upon methylviologen treatment. A correlation with H O accumulation was not observed. It is concluded that glutathione-dependent processes participate in light-triggered rapid gene regulation independent on cellular H O .

“…Thus, not all four ERF genes were transcriptionally regulated by heat, drought, NaCl, or mannitol (Figure 2). Together, the analysis of transcriptional regulation is in line with the idea that ERF102 to ERF105 have roles in multiple hormone and stress responses as was shown for these and other ERFs in a number of cases (Bethke et al ., 2009; Dubois et al ., 2013, 2015; reviewed by Licausi, Ohme-Takagi & Perata 2013; Mase et al ., 2013; Meng et al ., 2013; Moffat et al ., 2012; Moore et al ., 2014; Sewelam et al ., 2013; Son et al ., 2012; Vogel et al ., 2014; Xie et al ., 2019).…”

“…ERF102 and ERF103 regulate leaf growth inhibition upon mild osmotic stress (Dubois et al ., 2013, 2015) and ERF103 additionally regulates oxidative stress responses (Sewelam et al ., 2013). ERF103 , ERF104 and ERF105 are involved in the fast retrograde signalling response and the acclimation response to high light (Moore, Vogel & Dietz, 2014; Vogel et al ., 2014). Further studies have shown that ERF102 to ERF105 play a role in plant immunity (Bethke et al ., 2009; Cao et al ., 2019; Mase et al ., 2013; Meng et al ., 2013; Moffat et al ., 2012; Son et al ., 2012).…”

22The ETHYLENE RESPONSE FACTOR (ERF) genes of Arabidopsis thaliana form a large 23 family encoding plant-specific transcription factors. Here, we characterise the four 24 phylogenetically closely related ERF102/ERF5, ERF103/ERF6, ERF104 and ERF105 25 genes. Expression analyses revealed that these four genes are similarly regulated by 26 different hormones and abiotic stresses. Analyses of tissue-specific expression using 27 promoter:GUS reporter lines revealed their predominant expression in root tissues 28 including the root meristem (ERF103), the quiescent center (ERF104) and the root 29 vasculature (all). All GFP-ERF fusion proteins were nuclear-localised. The analysis of 30 insertional mutants, amiRNA lines and 35S:ERF overexpressing transgenic lines 31 indicated that ERF102 to ERF105 have only a limited impact on regulating shoot and root 32 growth. Previous work had shown a role for ERF105 in the cold stress response. Here, 33 measurement of electrolyte leakage to determine leaf freezing tolerance and expression 34 analyses of cold-responsive genes revealed that the combined activity of ERF102 and 35 ERF103 is also required for a full cold acclimation response likely involving the CBF 36 regulon. Together, these results suggest a common function of these ERF genes in 37 regulating root architecture and the response to cold stress. 38 39

“…Looking further among the core responsive genes, several members of the ERF/AP2 transcription factor family are found. The ERF/AP2 transcription factor family is known to sense and signal the response to changed metabolite levels resulting from increased irradiance levels; members of this family have been found before as regulators of early downstream targets in the acclimation response to high light (Alsharafa et al., ; Moore, Vogel, & Dietz, ). They are induced by the transcription factor ZAT10 (Alsharafa et al., ; Nguyen et al., ), which functions to initiate a systemic acclimation response to excess light (Munekage, Inoue, Yoneda, & Yokota, ; Rossel et al., ).…”

Photosynthetic response to increased irradiance correlates to variation in transcriptional response of lipid‐remodeling and heat‐shock genes

Plants have evolved several mechanisms for sensing increased irradiance, involving signal perception by photoreceptors (cryptochromes), and subsequent biochemical (reactive oxygen species, ROS) and metabolic clues to transmit the signals. This results in the increased expression of heat-shock response genes and of the transcription factor LONG HYPOCOTYL 5 (HY5, mediated by the cryptochrome photoreceptor 1, CRY1).Here, we show the existence of another response pathway in Arabidopsis. This pathway evokes the SPX1-mediated expression activation of the transcription factor PHR1 and leads to the expression of several galactolipid biosynthesis genes. Gene expression analysis of accessions Col-0, Ga-0, and Ts-1, showed activated expression of the SPX1/PHR1-mediated gene expression activation pathway acting on galactolipids biosynthesis genes in both Ga-0 and Col-0, but not in Ts-1. The activation of the SPX1/PHR1-mediated response pathway can be associated with lower photosynthesis efficiency in Ts-1, compared to Col-0 and Ga-0. Besides the accession-associated activation of the SPX1/PHR1-mediated response pathway, comparing gene expression in the accessions showed stronger activation of several heat responsive genes in Ga-0, and the opposite in Ts-1, when compared to Col-0, in line with the differences in their efficiency of photosynthesis. We conclude that natural variation in activation of both heat responsive genes and of galactolipids biosynthesis genes contribute to the variation in photosynthesis efficiency in response to irradiance increase.
